Be'it knownthat I; ARTHUR J HARTI EY, a 'citizen-of-the'United States of America,

and- State of Illinois, have invented certain new and usefulImprovements in Band Cut-- ters and-Feeders, of which the following isa specification;

This invention relates-to band cutters and feeders and is designed to deliver bundles of grain to a series ofband cutters, and then to feed'the grain-bythe use of oscillating feedersto the cylinder-of a threshen and mounting of the power connections forthe machine3withthe result that a desired speed maybe transmitted through various Working portions without; the use "of cunibersome' gear wheels. 1 Also this special mounting of hepower mechanism permits the governor to cientmanner.

A"

sprocket wheel 14 mounted on the power shaft 13 transmits power to a crank shaft 17 through the sprocket wheel 16 and chain 15. Frames 19 aremounted on the crank shaft '17 by means of boxings '18 and band knives 20 are mounted on the forward portionsof said frames. a I 'i Knife cleaning members .21 are suitably mounted adjacent said band knives and mounted upon the lowerend of said cleaning members are retarder knives 21 said knives having a stationary mounting adjacent the crank operated band knives and being positioned in such a manner that the bundles of grain fed thereto by the COD".

veyor member will be retarded slightly in their feeding movement, with the result that the crank operated band knives will be better able to sever the cords on the approaching grain bundles. These retarding knives also have the'function of straightening out the bundles of grain fed thereto and form a sort of guide members.

The rear portion of the frames 19 have mounted thereon. upper feedjpans 22, said pans being pivotally mounted with relation to arms 25 by means of the housing 2% and bearing 23. Other arms 27 are pivotally connected asat 26 to arms 25. One of these arms has pivotal connection at its other. end with the side of the thresher, and the other has a positive "connection with a a shaft 28 in connection with the'trip mechanism to be described later. A governor is mounted on the opposite end of the power shaft 13and is designated generally at'29, said governor however, to be described later in detail; A sprocket wheel 3O -having clutched or' unclutchedrela-tion with the power shaft and mounted thereon transmits power through the chain '31 to a sprocket 34, said chain passing about an idler 32mounted in an adjustable "bracket '-member 33. The power sprocket 34 is mountedon' theshaft 10f adjacent a clutch member designated generally as 35, to" be described later in detail. Sprocket 34 has clutched or unclutched relation with the crankshaft 10?, said shaft having mountedat-its opposite end and at the other side of'the-machine' a second sprocket 36, said sprocket transmitting power through the chain 37 and sprocket 38 to the shaft 10, whiehoperates the end"- less carrier. Attached' to the shaft 10 by means of boxes 39 are the lower feed pans 40, the outer ends of the pans sliding upon the stationary portion 41 of the re-' tardin meansfsaid stationary portion 41 being fixedly mounted on the end portionsv of the frame members 41 A base platetQis adjustably mounted at. A3 on the frame members and attached thereto as at -44 are the retarding members 441, said retarding members projecting through" suitableapertures 45in the" stationary portion 41. The above retarding mechanism is mounted adjacent the cutting blades of the lghresher. cylinder-and. as may be seen, may

e thereto.

Positively connected to one end of the crank shaft 17 is a lever46, whichat its outer end has pivotal connection as at 47 with thelever 48, and this lever has pivotal connection as at A9 with the outer end of an arm 50 which is positively connected as at 51 with the crank shaft52fl Crank shaft '5'2 h'as mounted thereon, by means of the boxings 53,- reciprocating litter pan 54:. This pan extends entirely beneath the ma,- chine and catches'all seepage of grain from the feed mechanism and transmitssaid discharge to the thresher cylinder. The outer end of the litter'pan slides on the lip 55 of the concave portion 56 ofthe'thresh'er.

The governor previously described generally as 29; has a housing member 57 fixedly attached as at 58 to the powershaft 13.

Mounted within the housing are weights 59, said weights being pivotallyconnected at their weighted ends by the pivots 60, arms 61 and lever 62,s aid lever being fixedly mounted upon theshaft 13. 'lheweight adjustably mounted with relation members have pivots 63 in connection with the governor housing, and the lighter ends of said weight w members have lugs 64: formed thereon. Coilsprings 65 surround rods 66, the coil springs abutting at their outer ends the lugs 64- and at their inner ends lugs 67 formed on the inner ends of the rods 66. A bracket'member 58 has formed thereon cylindrical portions for the reception of the coil springs and rods above described. This bracket member is attached to a member 69 in connection with the power shaft v13. One of the pivotal connections 63 of the weight members extends through the governor housing and "is positively connected to a lever "72 by the mounting 71 in connection with its squared inner end 70.

77 and adjusting nut 78.

Itmay beseen from the above description that any movement of the weight members due to centrifugal force. will 'ca'useja'corre sponding movement to the lever 72,- which the sprocket L wes will cause a clutching or unclutching relation of the friction "drum 7 3, "andtherefore the sprocket 30, with thepower shaft 13.

The clutching mechanism, described generally, as 35, is mounted in connection with wheel 34, rotatably on the shaft 10 and jecting therefrom, and friction rollers mounted on the projecting ends of said] cores. As shown in Fig. 12', the clutching mechanism consists of a clutch member 82" pivotally connected at 83, said clutch member having an inwardly projecting lug 82 capable of contact with the friction rollers 81 in connection with the' sprocket wheel 34. The clutching member also has an outwardly projecting member 82 capable of contact with the trip lever of the trip mech-' anism to be described later; An abutment 8 1 on the clutch member limits the outward movement of said member. The clutch member has its pivotal mounting 'at'83, said mo'untingbeing formed on the bracket member 85, whiclris an inwardly projecting hub portion ofa clutch disk 91, said disk being fixedly mounted with relation to the shaft 10 asat 86; A spring 89 'is attached'to the clutch member at 88, and to the outer disk at 90, said spring tending to hold the clutch member in its outermost position.

It maybe seen from the above description that the clutch member,- when the lug 82 is capable of'contact with the friction roll -ers on the rotating sprocket 34, will,

through its members, cause rotation'of the shaft 10, and when the clutch member is thrown backward by contact of the trip lever against the lug 82, the member'82 will be held below th moving rollers and the shaft 10 thrown "into unc'lutched relation with the rotating sprocket wheel.

lVhile' the clutch member is held in its backward position, there is a tendency, due to the rapid rotation'ofthe sprock'etfwheel 3 1, for the lug 82 to move forward slightly and strike the friction rollers 81; striking these rollers, the lug will be thrown quickly backward, thereby setting up a chattering and'making rather a noisy clutch; To overcome this" chattering)a 'spring washer, or other spring means, is mountedas at 91,betw'een the inner portion ofthe V clutch mechanismand the inner hub of the spro'cketwheel.

"The lower ends of the upper feed'pans previously described, through various arm's,

have a pivotal mounting at one side with the 4' side "of the threshe'r, and at: the. other side I are positively. connected to the shaft 28; pivotally mounted in a '1 bearing. in they side of the asset A portion of the shaft projecting from the "side 'oft'he feeder is cylindrical, as shown at 93, tliefonteif end,

positively driven by the chain I 81. Sprocket wheel 34 has inwardly ro: jecting lugs'79, said lugs have a core pm Upon however, being squared as at 92. Arm 9 1,

Connected thereto, as at 95, is the arm 96, said arm being'fpivotally connected to; the lever 97 which ispivotally mounted on the having the seat 94? thereon, is mounted on the cylindrical porti0n93 of the shaft 28;.

shaft 98, said shaft being connected to the feede'r'fra'me by the U-bolts 99. A 'rod' 100 ispivotally connected to the opposite end of the lever 97, and has encircling its lower portion the coil spring 101, the threaded nut 102 formingan adjustable ten'sioning" means for the coil spring. A lever' l03 is positively'mounted on the squared end??? of the shaft 28,"said' lever having one arm 104 surrounding the rod'100' and forming an upper V abutment for the coil spring lOlL The other arm of lever 103 has thereon an' adjustable mounting 1'05 capable of can tactwiththe seat 94 ofthefleve'r 94. Pivotally'connected at 106 is an arm 107,said arm having at its lower end the U-shaped attachment end 108, Tlie'lowe'r portion of the arm 107 is slidably mounted in'theslot 109 in the trip'leverllO, said trip lever haV ing a 'se'mi ri'gid connection with the core 111; This semi-rigidconnection is obtained through the'peculiar mounting of'the trip lever on said core. A friction layer 112 surrounds the base portion of the "core 111,"

and'has frictional contact with theinner portion of the trip lever hub'110".

Bolt 113 projects through the core 111, and has the bracket 114 adj ustably mounted at 'its outer end, by means of the adjusting nuts 115'and coil spring11'6j The innerend'of the coil spring places considerable tension upon the outer hub'portion ofthe'trip lever and furnishes' additional aid] in'the pro-,,

vision of a semi-rigid connection.

The "trip lever has projecting outwardly atits' outer end the lug '117 for en' 7 ga ement" with the "projection" 82" or the a clutch mechanism 'i'vhenever this relation is In order to more clearly describe the nnecessaryb ventiom'the operatienjwill nowbe set forth i l When power is" transmitted to the power knives and also affording movement to the 13" has attained suflicient speed to throw the clnt'ch mechanismffof' the floverner;

In otlienwojrds, bundleslbf grain thrown; on tnesffeqaveyqr will "not" bejj'iearried to? the;

no r

cutter knives until said members have attained a relatively high speed. The reason for this is obvious, inasmuch .as bundles of grain delivered to sluggishly acting cut- 6 Zing knives and feeders would result in a clogging of the machine. 1

The machine having attained the desired speed, the bundl s of grain are carried to the cutter knives, and the encircling bands 39 of the bundles cut by said knives and the grain f d, by the oscillating feed pans, to the threshing cylinder. However, should the amount of grain acted upon by the feed pans become excessive, the upper feed pan 315 as described, having pivotal mounting at its lower end, will be forced upwardly and the upward movement of said pan being transmitted directly, through the previously "described mechanism to the trip lever, said so trip lever, should the amount of grain in the feed pans raise said pans high enough, will engage the clutch mechanism previously described and the operation of said clutch mechanism will immediately throw the con g5 veyor mechanism and lower feed pan out of 7 operation. This will permit the constantly oscillating upper feed pans to carry off the excessive amount of grain held between the feed pans until the upper feed pan has dropped sufficiently low to throw the trip out of engagement with the clutch mechanism.

Inasmuch as one of the objects of this invention isin the provision of a special 5 trip mechanism, its action will be described more in detail.

As the upper feed pans are forced upwardly by an excessive amount of grain 'fed thereto, the shaft 28 having the trip 40 mechanism mounted on its outer end is moved in a corresponding manner. The lever 103 fixedly mounted on the outer end of the shaft 28, through its arm 10%, forces downwardly therod 100. The spring 101 on the rod 100 is sufliciently tensioned thereon that the arm 100 will be-forced downwardly before the spring will be compressed. The downward movement of the arm 100, through its related members, raises the arm 96, and thereby forces downwardly the lever 94-. and rod 107. The rod 107 in its downward movement eventually acts upon the trip lever 110 and throws it into engage- -ment with the clutch mechanism. As has 5 been said before, the coil spring 101 is strong eneugh to permit the downward movement of the before mentioned arms before it is greatly compressed. trip lever has ben thrown into engagement 0 with the clutch mechanism, and the upper feed pan still being raised by an excessive amount of grain fed thereunder, the excess movement of the lever 103 will be taken up I by itsarm 104C compressing the coil spring 101. Thus, it will be seen that any chance of However, after the the trip mechanism being broken by an excessive upward movement of the feed pane ment of the upper feed pans to take care of. the different conditions of gram being op erated upon.

The slot 109 in the trip lever takes up any vibration of the rod 100, with the result than any possibility of the trip lever being thrown out of engagement m chanism 1S obviated.
